f(x)= 1/(1+cos(x))

Solution

f (x) = \frac{1}{1 + cos ( x )}

Solution

Period : 2 π

Domain : 2 πn \leq x < π + 2 πn or π + 2 πn < x < 2 π + 2 πn

Range : f (x) \geq \frac{1}{2}

f(x)=3x^4-4x^3-12x^2

f (x) = 3 x^{4} - 4 x^{3} - 12 x^{2}

f (x) = x^{4} - 9 x^{2}

f(x)=(sin(3x))/x

f (x) = \frac{sin ( 3 x )}{x}

f (x) = e^{x^{x}}

f(x)=(x^2)/(sqrt(x+1))

f (x) = \frac{x ^{2}}{x + 1}
